ARC-LAMP HANGER.

SPECIFICATION forming part of Letters Patent N o. 566,652, dated August 25, 1896. Application led February 13, 1896. Serial No. 579,142. (No model.)

T0 @ZZ whom, t may concern:

Be it known that I, WINFIELID S. BOSLEY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Arc-Lamp Hangers, (Case No. 2,) of which the followingis a full, clear,

concise, and exact description,reference beingl had to the accompanying drawings, forming a part of this specification.

My invention relates to an arc-lamp hanger; and its object is to provide a hanger whereby the lamp may be raised and lowered and automatically thrown into and out of circuit.

According` to my invention the lamp is suspended from a drum or roller, means being provided 'for rotating the drum to wind thereon or unwind therefrom the cords or cables from which the lamp is suspended. To the suspending-cords is attached the cross-piece, which, when the lamp is raised, comes in contact with a pivoted lever to rotate the same and actuate a switch which throws the lamp into circuit. Vhen the lamp is lowered, the lever is moved to cut the lamp completely from circuit and to close a by-path to complete the circuit about the lamp.

I will describe my invention in connection with the accompanying drawings, in which- Figure l is a view in elevation of thehanger of my invention as seen from one side. Fig. 2 is a similar View as seen from the opposite side. Fig, 3 is a view in section on line 3 3, Fig. l, the drum being removed. Fig. 4 is a longitudinal sectional view of the hanger. Fig. 5 is a transverse sectional view thereof on line 5 5, Fig. 4.

Like letters refer to like parts throughout the different gures.

Upon a base-board a and insulated therefrom are mounted the standards or bearings o b, in which the roller or drum c is journaled to rotate. The roller may be of any desired construction and in the present instance is shown as composed of a cylinder of Wood, upon the ends of which are provided metallic plates c c2, which, as the drum rotates, make electrical connection with the bearings b b", respectively. To the plate c is electrically connected the end of the cable C7, the cable then being wound about the drum and extending downward to the binding-post of the lamp. The cable c7 is electrically connected with the plate c2, and after winding about the drum extends downward and 'is connected with the opposite bindingpost of the lamp. A rope or cord f is wound about the central part of the drum and extends downward, whereby it may be grasped to rotate the drum and raise the lamp. Upon the drum is provided a ratchet-wheel g, with which a pawl g' normally engages, the pawl being provided with an extended end g2, adapted to be engaged by the cord f to move the pawl out of engagement with the ratchetwheel. Upon the base-board a and insulated therefrom are mounted springs 7L 7L', bindying-posts 7b2 h3 being provided, one in connection withv each of the springs, to which binding-posts the incoming and outgoing wires h4 71.5 are connected. The ends of the springs 7L 7n normally rest in contact with the upturned ends of a metallic strip h6, which is mounted upon and insulated from the base-board a. lVhen in this position, the circuit may be traced from one bindingpost through the springs and strip 71,6 to the opposite binding-post, the lamp being thus out out. Upon the base-board a are mounted springs M', the springs being. insulated from the base-board and their ends disposed, respectively, opposite the ends of springs h h. The spring t' is connected by a conductor m with'the bearing 79, while spring t is connected bya conductor 'm' with the bearing b. The ends of said springs i t" rest upon an insulating-block 7e, carried upon the end of a lever 7c', pivoted at 7c2. The opposite end 7.;3 of the lever is extended downward, the lower end being bent outward, as shown in Fig. 5. Opposite arm 7cS of the lever 7c is provided an arm-or standard 7.34, mounted upon the casing 705, that incloses the drum, said standard having an oblique lower end.

When the lamp is raised, the cross-piece l, secured to the cables d CW, passes between the standard 7.@4 and the arm 7c3 of lever 7c", thus rotating said lever upon its pivot to thereby bring the springs it" into contact, respectively, with the springs 7L 7i. Circuit may now be traced from incoming wire h4 to binding-post h2, thence to spring 7L, spring fi, by conductor IOO m to the bearing Z), thence to cable d, through the lamp c to cable d', thence to bearing b', conductor fm', spring Q1', spring h', bindingpost h3 to the outgoing wire h5, the lamp being thus connected in circuit. 't

Then the lamp is lowered, the cross-piecel is moved from between the standard 7a4 and arm 7c3 and the resiliency of springs it" rotates the lever 7a upon its pivot to break the contact between the pairs of springs h z' and 7L c" and permit the springs 7i h to make contact with the uptnrned ends of the strip 7L, to thereby cut out the lamp.

Having,` thus described my invention, what I claim as new, and desire to secureby Letters Patent, is

l. The combination with a pair of springs connected, respectively, with the opposite sides of the light-circuit, of a short-circuiting strip with which said springs are normally in contact, a second pair of springs disposed, respectively opposite said irstmentioned springs and connected with the opposite sides of the lamp, a pivoted lever adapted, when rotated, to move said firstmentioned springs out of contact with said short-circuitingstrip and into contact with said second-mentioned springs, and a crosspiece carried upon the cables from which the lamp is suspended adapted to engage and rotate said lever, substantially as described.

2. The combination with the springs L 7L' mounted upon the base-board, of the shortcircuiting` strip h6 with which said springs 7L h' normally make contact, springs fifi with their ends disposed respectively opposite the ends of springs h h, the pivoted lever 7c carryinginsulating-block 7c upon which said sp1-in gs 'L' t" rest, the end 7c3 of said pivoted lever 7a' being,` extended downward, the standard la and the cross-piece Z secured to the cables from which the lamp is suspended adapted to be passed between said standard It* and arm 7o of the lever, substantially as described.

In witness whereof I hereunto subscribe my name this 2Stl1 day of September, A. D. 1804.
